10 Everyday Things Horror Movies Have Made Terrifying

10. Showers

Nobody is more vulnurable than when they are in a shower. The hot water relaxes and the skin and the muscles as the person exfoliates and lets the shampoo form a swath of suds in their hair. On top of all that, they're naked. Not much is there in the way of protecting the body, or even keeping the private parts from being exposed.

Despite all of this many people approached showers without any fear or trepidation for hundreds of years. That all changed when Hitchcock's legendary slasher and psychological horror film, Psycho came out in 1960.

The original scene is laid out perfectly with Janet Leigh taking her shower without any background music. A couple of tight angles give this trapped feeling before the curtain is pulled back and a shadowy figure hacks away at Leigh, with the soundtrack producing these ear-bleeding shrieks and the victim lets out screams of her own, creating a scene both brutal and voyeuristic.

From then on, the shower scene has become a staple of the horror genre, playing on the viewer's inner previsions. Ever since Psycho, people have kept the bathroom door locked for their showers, just in case there's a knife-wielding maniac in the house. Getting stabbed is one thing, but nobody wants to be naked and get stabbed.
